air horn for pvc 1/2" pipe

thingiverse

Love this little air horn, here is a 1.1 version. changes include:1) added a piece (shown in red) to attach to the blow hole as a fitting so its easier to blow or hook up to an air system to be attached with glue2) made another horn piece (orange) similar to the original in that it wedges in place the same, only the outside is back to the original pipe size.3) resized so the piping matches 1/2" pvc pipeSteps 2 and 3 are sisters in crime as with this setup, you can cut a section of 1/2" pvc pipe and make the horn longer pushing the ends of these two pieces into the pvc pipe. This will give this horn a much deeper richer tone based on the length of pipe you add.What I do with this is use a hose clamp to a rubber hose onto the mouthpiece and hook up a push valve in line, and then the other side of the valve to a pressured wheel barrow innertube. by pushing the valve the air is let into the pipe. making a huge sound.
